"Two of our long-standing buy recommendations are involved in selling products and services for the genetic research market: Affymetrix (AFFX) and Illumina (ILMN)," notes biotech and growth stock specialist Nate Pile.

The editor of Nate's Notes explains, "In a nutshell, both of these companies have developed technologies that allow researchers to do what is known as 'high-throughput genetic screening'.

"And, while the two companies are direct competitors in many of the markets in which they compete, we believe that both stocks should be bought at the current time.

"Illumina (NASDAQ: ILMN) makes the Genome Analyzer, which is the workhorse of the genetic medicine revolution," says growth expert Mike Cintolo in The Cabot Top Ten Report.

"The Illumina Genome Analyzer is used by genomic research centers, academic institutions, agriculture and livestock companies, pharmaceutical companies, clinical research organizations and biotechnology companies all over the world.

"In the fourth quarter of 2008, for example, the company launched the In? nium HD HumanCytoSNP-12 BeadChip, a 12 sample BeadChip priced as low as $125 per sample that enables researchers to analyze nearly 300,000 genetic markers per sample.
